Multiple Text Cryptanalysis by Using Matrix and Logical Operations

Data security is plays a vital role in data communication through Internet. Definitely there is a need to protect the data from unauthorized access .To protect data cryptography plays an important role. Cryptography is a technique which allow human-being to encrypt the data in such a way that the decryption can be performed without the aid of sender. In proposed algorithm logical OR operation is used to generate key, XOR operation is used to encrypt data which is a reversible process. By using Railfence algorithm data will be shuffled.
